When viewing an issue, you often want to check the assigned workflow. With Admin Toolbox you'll have an Edit button directly added to the workflow view. When you click on the button, the workflow will open in edit view in a new tab.
This feature is only available for Jira administrators. For all other users this button is not visible.
If you still have questions, feel free to refer to our support team. You can also download our app from the Marketplace.
